Abstract (en)
[origin: EP1442854A1] Waste wood is recycled into a large cross-section wood board without using a hazardous material as a binder. The invention provides a method for manufacturing a recycled wood product, and includes the steps of atomizing, to a wood material containing small wood chips, a mist of high-polymer agent having a natural component as the chief ingredient thereof, pressuring the wood material sprayed with the high polymer mist with the wood material aligned in the length direction thereof, and steam heating the wood material under a high-pressure environment to bond the adjacent wood chips together. A high-polymer agent containing tannin as a chief ingredient is used in one example. A high-polymer agent may be applied on the wood material. The method preferably further includes a curing step for cooling the wood material continuously in the high pressure environment to room temperatures using one of air cooling and natural cooling subsequent to the steam heating step for steam heating the wood material under the high-pressure environment to bond the adjacent wood chips together. <IMAGE>
